The idea is to actually use it for playback, not just storage, and nothing else has the nice asymmetrical fast decompression with such effective compression (wavpack supports 705/768 but is woefully slow on decompression and poorly supported). Mostly the sample rates would be multiples of the common 44.1/48 sample rates so I expect compression to be equally good with simple extrapolation to bigger equivalent sized windows.
